Tested by:	pho

Konstantin Belousov
41014d996a vn_io_fault() is a facility to prevent page faults while filesystems 
perform copyin/copyout of the file data into the usermode
buffer. Typical filesystem hold vnode lock and some buffer locks over
the VOP_READ() and VOP_WRITE() operations, and since page fault
handler may need to recurse into VFS to get the page content, a
deadlock is possible.

The facility works by disabling page faults handling for the current
thread and attempting to execute i/o while allowing uiomove() to
access the usermode mapping of the i/o buffer. If all buffer pages are
resident, uiomove() is successfull and request is finished. If EFAULT
is returned from uiomove(), the pages backing i/o buffer are faulted
in and held, and the copyin/out is performed using uiomove_fromphys()
over the held pages for the second attempt of VOP call.

Since pages are hold in chunks to prevent large i/o requests from
starving free pages pool, and since vnode lock is only taken for
i/o over the current chunk, the vnode lock no longer protect atomicity
of the whole i/o request. Use newly added rangelocks to provide the
required atomicity of i/o regardind other i/o and truncations.

Filesystems need to explicitely opt-in into the scheme, by setting the
MNTK_NO_IOPF struct mount flag, and optionally by using
vn_io_fault_uiomove(9) helper which takes care of calling uiomove() or
converting uio into request for uiomove_fromphys().
